Lock device

Abstract

A security lock for retaining a weapon in a storage rack can be operated either electrically by a remote switch or mechanically by a key. The weapon is locked to a main body by a lid which is pivotally mounted by a hinge and pivot pin on the body. The plunger of a solenoid extends into a slot formed in the pivot pin preventing it from rotating when the lid is in a locked position and the solenoid deenergized. A key actuated detent locks the pivot pin to the lid when the detent is in key locked position. Actuation of the solenoid retracts the plunger permitting the lid to pivot to open position without operating the key operated detent which maintains the pivot pin locked to the lid. Retraction of the key operated detent unlocks the pivot pin from the lid to enable the pivot pin to be slid axially along the hinge to disengage the solenoid plunger from the pivot pin slot permitting the lid to move to open position without energizing the solenoid.

What is claimed is: 
     
       1. A lock device operated independently, electrically and mechanically including: (a) a lock body;   (b) lid means for locking an object on the body, pivotally movable between locked and unlocked positions;   (c) hinge pin means for pivotally mounting the lid means on the lock body, said hinge pin means being slidably mounted with respect to the lid means and rotationally mounted with respect to the body;   (d) mechanically actuated first detent means for locking the hinge pin means to the lid means; and   (e) electrically actuated second detent means for locking the hinge pin against rotation with respect to the body, whereby mechanical actuation of the first detent means unlocks the hinge pin means from the lid means permitting said pin means to be slid out of locked engagement with the second detent means permitting the lid means to be moved to the unlocked position, and whereby electrical actuation of the second detent means unlocks the hinge pin means from the body permitting the lid to be moved to the unlocked position with the first detent means maintaining the hinge pin means locked to the lid means.   
     
     
       2. The lock device defined in claim 1 in which the lock body has an open sided slot for receiving an object therein; and in which the lid means opens and closes said open side of the slot when in the unlocked and locked position, respectively. 
     
     
       3. The lock device defined in claim 2 in which the body is formed with one wing of a hinge assembly and the lid means is formed with the other wing of the hinge assembly; and in which the hinge pin means is engaged with the wings when said wings are in an aligned position to pivotally mount the lid means on the body. 
     
     
       4. The lock device defined in claim 3 in which the hinge pin means is a generally cylindrical shaped pin, in which the first detent means is a key actuated detent mounted in a lock cylinder located in an open end of the hinge pin; and in which said detent projects through a hole formed in the hinge pin and into a hole formed in the wing of the lid means for locking the hinge pin to the lid means. 
     
     
       5. The lock device defined in claim 4 the second detent means is a solenoid plunger; and in which the plunger extends into an open ended slot formed in the hinge pin whereby the sliding movement of the hinge pin disengages the plunger from the slot enabling said pin to rotate with respect to the lock body. 
     
     
       6. The lock device defined in claim 5 in which the plunger is spring biased into the hinge pin slot; and in which actuation of the solenoid retracts the plunger from the slot. 
     
     
       7. The lock device defined in claim 5 in which the hinge pin has a first stepped cylindrical portion with a diameter complementary to a bottom surface of the plunger receiving slot. 
     
     
       8. The lock device defined in claim 7 in which the hinge pin has a second stepped cylindrical portion engageable in an opening formed in the said one wing of the lid means. 
     
     
       9. The lock device defined in claim 1 in which spring means biases the lid to remain in open position. 
     
     
       10. The lock device defined in claim 1 in which retention means is engaged with the hinge pin means to limit the sliding movement of said pin means with respect to the lid means. 
     
     
       11. The lock device defined in claim 10 in which the retention means is a set screw extending through an opening formed in the lid means and terminating in a groove formed in the hinge pin means. 
     
     
       12. The lock device defined in claim 1 in which the second detent means includes an electric solenoid mounted in the lock body and a solenoid actuated plunger extending through a hole formed in said body and into a slot formed in the hinge pin means. 
     
     
       13. A lock device for securing a weapon in a rack including: (a) a lock body having a weapon receiving slot form therein;   (b) a lid pivotably mounted on the body and movable between a closed position wherein said lid closes the slot to prevent a weapon from being removed from the body, and an open position wherein said lid permits the weapon to be removed from the body slot;   (c) a hinge pin pivotably mounting the lid on the lock body, said hinge pin being slidably mounted with respect to said lid and body;   (d) a lock cylinder mounted in the hinge pin and having a key actuated locking detent, wherein said detent when in an extended position, secures the hinge pin to the lid preventing sliding movement therebetween; and   (e) an electric solenoid actuated plunger mounted in the body and moveable between an extended position wherein said plunger engages the hinge pin to prevent rotation of said hinge pin and lid to the open position when the key actuated locking detent is in the extended position, and a retracted position wherein the plunger is disengaged from the hinge pin whereby the lid can be pivoted to the open position, and wherein movement of the key actuated locking detent to a retracted position disengages the hinge pin from the lid permitting sliding movement of the hinge pin with respect to the lid causing disengagement of the solenoid locking pin from locking engagement with the hinge pin whereby the lid can be rotated to the open position.   
     
     
       14. The lock device defined in claim 13 in which the hinge pin is formed with a slot; and in which the solenoid plunger extends into the slot to prevent rotation of the hinge pin. 
     
     
       15. The lock device defined in claim 14 in which the hinge pin has a reduced diameter stepped cylindrical portion the surface of which aligns axially with a bottom surface of the slot. 
     
     
       16. The lock device defined in claim 13 which a tension coil spring extends between the lock body and lid and is connected to the lid in an off-center relationship to bias the lid to remain in the open and closed positions upon reaching said positions. 
     
     
       17. The lock device defined in claim 13 in which the key actuated locking detent projects through a hole formed in the hinge pin and into an aligned hole formed in the lid to secure the hinge pin to the lid when the detent is in the extended position.
